I am just starting out in the wonderful world of rifles and in so pretty ignorant when it comes to them. My main starting point is should I go AR/AK/AR Pistol? Do I go .556, 300BLK, or 7.62? the natural question to help answer is "what am I trying to accomplish?" I really just want one for the round about mix of purposes: another form of home protection, something to help acclimate to rifles, something fun to plink with on the range, in case good 'ol Hillary gets elected, etc. 300BLK would be cool because I could even use it to hunt if I ever decide to hunt in the future. So maybe what I am after is just some suggestions on what some people out there use and what for. clearing up whether I should go full length rifle or pistol format, and what purposes different calibers serve. I will probably be looking at trying some out in the next month and have a $500-$800 budget. Let me know if anyone has anything to add. thanks!
